This guide shows how to inspect Maven's dependency tree using IntelliJ IDEA's built‑in tool, the command line, or the Maven Helper plugin, identify version conflicts, and resolve them with exclusions or dependencyManagement entries.
This article explains the pain points of Jar package conflicts in Spring Boot projects, outlines the limitations of existing tools, and presents a lightweight, embeddable solution that performs runtime scanning, three‑dimensional conflict detection, configurable rule‑based advice, and a web UI for visualizing results.
This article explains common Maven JAR dependency conflict scenarios and presents four practical solutions—including using Exclusions, configuring dependency scopes, applying the Maven Shade plugin for class relocation, and employing class‑loader isolation strategies—to help developers choose the appropriate method for their build and runtime environments.
The article explains how incompatible JAR versions, such as differing Guava releases required by business code and middleware, can be resolved efficiently by using Maven Shade Plugin to relocate packages, offering a lightweight alternative to heavyweight class‑loader isolation solutions like Pandora or SOFAArk.
Learn how Maven’s dependency resolution can cause jar conflicts, recognize common runtime errors like ClassNotFoundException, and use IDE tools, Maven commands, parent POM management, exclusion and version locking techniques to identify and eliminate conflicting jars in Java backend projects.
This article explains why manual jar management can cause class loading conflicts, shows quick IDE-based steps to reorder jars for a temporary fix, and dives into JVM classloader isolation, the parent‑delegation mechanism, and Tomcat's startup loading order to help developers debug and prevent such issues.
This guide explains why multiple Netty jar versions cause runtime errors, shows how to use the Arthas tool to inspect loaded classes and methods, and provides Maven commands and pom.xml techniques to locate and eliminate version conflicts in Java backend projects.
This article explains why using fastjson's Feature.OrderedField caused a NoSuchFieldError during unit tests, demonstrates two methods—Maven dependency tree and runtime class location—to pinpoint the conflicting JAR, and shows how switching to Gson resolved the issue.
A Spring Boot 1.5.7 application suddenly stops starting because the main thread is blocked, the stack trace shows a NoSuchMethodError for ObjectUtils.unwrapOptional, which is traced back to a mismatched spring‑context 5.x jar overriding the original 4.x version, and the article explains how to identify and resolve the dependency conflict.
